1.0 General
1.1 All rights reserved
The manufacturer has a policy of continuous product improvement and reserves the right to make
changes to the specications without prior notice. The technical details are considered correct but
do not form the basis for a contract or warranty. All orders are accepted subject to the standard
terms and conditions of sale and delivery (which will be sent to you at your request).
1.2 General warnings
Installation must comply with the relevant local and/or national regulations. You must therefore
have the ColdStream installed by a professionally qualied installer in accordance with all applicable
national and international regulations. Faulty installation, adjustment, alteration, maintenance activity
or repair shall render the warranty void.

1.3 Presentation of the ColdStream Evaporative Cooler
To improve the summer microclimate inside a production unit, sales or other area, it is necessary
to ventilate the environment with frequent changes of fresh, ltered and possibly cool air. For large
areas such as industrial buildings, an air conditioning plant is frequently not adaptable due to the
great volume of air to be cooled and the thermal loads of processes to be neutralized, the necessary
amount of energy is very high and the cooling effect is reduced by the exhaust air extraction plant
and by frequent opening of the doors during normal activity.
Evaporative cooling plants that cool the air using a natural principle represent an optimal solution:
the air passes through special wet water lters, loosing part of its heat during the evaporation
process of the water and hence lowering the air temperature. The absence of refrigeration plants
reduces energy consumption to a minimum and enables great volumes of air to be treated for the
many air changes necessary.
Warning
Incorrect installation, adjustment, alteration, repair or maintenance work may lead to material
damage or injury. All work must be carried out by certied, qualied professionals. If the
appliance is not positioned in accordance with the instructions, the warranty shall be rendered
void. This appliance is not intended for use by children or persons with a physical, sensory or
mental handicap, or who lack the required experience or expertise, unless they are supervised
or have been instructed in the use of the appliance by somebody who is responsible for their
safety.Children must be supervised to ensure that they do not play with the appliance.

5.0 Functioning notes
The functioning of the evaporative cooler is based on an important principle: It introduces big
quantities of fresh air into the building and removes hot exhausted air through doors, windows and
other openings. If the system is not able to expel the air volume introduced into the building, the
efciency would be compromised. INLET FRESH AIR = OUTLET HOT AIR: a very simple principle.
If the system is able to expel all the air introduced into the building, the system operates at the
highest efciency. The ideal condition is when, into the building, the air diffusers are positioned away
(better on the opposite side) from the openings (windows, doors, etc.) so the air passes through
the building while cooling it. Maximum efciency can be reached by adjusting the dimensions of
the window and door openings. Never close the openings: if they are closed, no changes of air will
occur, consequently reducing the cooling effect and increasing the relative humidity level inside the
building.
